IMPROVEMENT l`N CORN AND PHOSPHTE-DRILLS;

The Schedule referred lto in these Letters Patent and making part of thesame.

. We, JOHN W. WOOD, of N ew Leeds Corner, and GABRIEL MOORE, of FairView School House, in the county of Cecilv and State of Maryland, haveinvented certain Improvements in Corn and Phosphate-Drills, of which thefollowing is a specification.

The nature of our invention is as follows:

The hopper or hoppers have three apartments, the middle oneto containthe seed, and the side one guano cr phosphate. Beneath each hopper is aslide having an openingto connect with eac-h compartment of the hopper,each opening being provided with au adjustable slide, so that the amountof seed and phosphate to be dropped may be regulated independent ofeachother. lhe combined slides are worked by means of cams on the sides ofthe central traction-wheel. One of the said cams also operates a pawlwhich moves an indicator that is used in preparing the field forplanting.

Thereis one plow, or more, and double mold-boards,

for turning over the ground fiom each side of the furrowsl on thenewly-planted seed, and the phosphate deposited in the intersectionofthe furrows in the forward movement of the machine.. The mold-boardsare situated a short distance behind the plow, and have a rigidconnection therewith by means of rods or bars the ends oi' which-areconnected by means of pivots. y The height ofthe plow is adjusted bymeans of a double rack at. the front of the machine with which the frontend. of their draft-bars are connected. The height of the mold-boards isadjusted by means of a leverwhich is vconnected with the stem of acasterwheel yoke at the rear end of the frame of the machine, the leverbeing combined with a stationary ratchet in such` a manuel-.as to beconfined in its adjusted posi.

tion. Both the plow and mold-boards are elevated above the groundandheld by the same device in their elevated position when not desired tovoperate. The rear end of the machine is elevated by they same movement,whereby the traction-wheels are elevated Figurel is a plan of themachine with one of the` hoppers 'S removed therefrom.

`Figures 5 and 6 are a top and sideviews of one of the slide-rods t.

Figures 7 andS are like ,views of the slide X and pawl z in connection.

\ Figures 9 and l0 are top and side views of the donf ble levers O O.

ALike letters in all the figures indicate the same parts.

.A is a horizontal frame, to which the other parts of the machine areattached;

B is a central traction-wheel C C are front caster-wheels and C5', arear caster-wheel, which assists in supporting the weight of theinachine.-

The journals a of the shafts D D have their bear.- ings in the yokes EE, whose central stems b b have afree turn in the outer ends of theirons F F. The said irons are bolted to the upper side of the frameA.The stein b ofthe yoke E ofthe rear'caster-wheel C turns freely in asocket in the lower end of the vertical shaft the said shaft having amovement in the bushing h', as hereinafter described. Y

GHG are plows at each side of the frame A. Right and left mold-boards JJ areeonnected with each plow,

' in the rear of the saine, by means of the straps or rods K K, yoke L,and pivots c. The front part of the plow is connected to the stationarydouble rack Mattached to the front of the .frame Ayas seen in figs. land 2, by means of the draft-irons Nthe joint end of which is providedwith the cross-rfod f, whose ends are caused to rest in slots g of therack, to hold the plow in its. adjusted position. v l

lhe'mold-boardsat each side of the machine 'are hungto the outer endsofthe horizontal levers O 0, which have fnlcruinpins h confined to thehangers-P Pqthat project from the lower side of the `frame A,

the'levers-having slots i, which connect with the said .of thestationary ratchet Rf The arm Z'of the lever is jointed to the shaft d,in4 connection with the upper C'. The lever is provided with atooth, lm,which connects with a tooth, ai, of the ratchet It when thelever is`brought into the proper position to adj ust the height of the wheel C',and thus to regulate the height of the mold-boards J'. By the samevdevice inthe forward end of the stem b of the yoke'E of thecaster-wheel y the two latterA the phosphate.

movement of the .lever the rear part of the machine-is sufficientlyelevated to bring the mold-boards and plows above the ground when not,required to operate. Y

S S are the hoppers, which supply the seed and compartment o,andvopenings qfq in tov the compartments o o'. v

In vcombination with the hopper-s SS are horizontal slides T T, whichare operatedbymeans of the series of cams on the rings U U, which areconfined by the rods -r to the spokes sof the traction-wheel B, as seenin iig. 2.

The rodst t of the slides have frictionwheels u u at their inner ends,which connect with the cams, as seen in iig. l. The said slides haveopenings o c o', which correspond with the openings q q' q ofthe bottomsp of the hoppers S AS, to admit ofthe passage of the seed and phosphateto the hills when the former are broughtinto connection with the latterby the action of the cams.

The openings c o o in the slides T T are provided with slides w w w',which are adjustable by means of the set-screws y, as seen in fig. 4,whereby the quantity of seed and phosphate fed through the slides iseach regulated independent of the other.

W is a revolving indicator, which is operated by means` of one of thecam-rings U abovel'deseribed, acting through the pawl z, which is hungto the slide X. Each forward movement of the slide causes the pawl tocarry the indicatoraronnd-- two teeth past the pointer Y, and therebeing thirty-two teeth, sixteen hills are dropped in each furrow at onerevolution of the indicator, there being a correspondingaction betweenthe slide X and the feeding-slides T T. For the purpose of throwing theslides T T ont of' gear with the cam-rings U U when the machine isrunning on the road, the rods t t have cross-slots l l, with which thevlevers ZZ connect when the slides are in gear. Vhen the slides are tobe disconnected, the levers are thrown ont of ,connection with saidgrooves, allowing the rods to vibrate backward and forward'in the slots2 2, which are prolonged into the slides far enough to allow of freeplay for the rods without moving the slides.

lVhat we claim as our invention, and desire to secure by Letters Patent,is`

. 1. The construction of the hoppers S with triplicate compartments `o oo' for distributing the seed and phosphate at one operation, incombination with the slides T, constructed, arranged, and operatingsubstantially in the manner and for the purpose above described. i

2. The combination and arrangement of the double 1noldboards J J withthe plows Gr by-means of the straps or rods K, yokes L, and pivots `e,substantially as and for thepurpose set forth.

3. In combination with the mold-boards J thelever Q, ratchet R,double-jointed levers O O, socket j, and st em 7; of the yoke E, theseveral parts being constructed and arranged for joint action,substantially in the manner and for the purpose speciiied'.

4f The combination and arrangement of the slide X and pawl z with the'cani-ring U and indicator W, substantially as and for the purpose setforth. 5. The cambination and arrangement of the levers Z with the rodst ot' the slides T by means of the'slots 1 substantially inthe mannerdescribed, and for Vthe purpose specified.

In testimony that the above is our invention we we have hereunto set ourhands and aixed our seals this 12th day ofNovember, 1870.
